TRANSDUCERS
for spirometry
The transducer is the part of the spirometer through which the patient blows; it measures the air flow.
Sibelmed is the only manufacturer with 3 different transducers: Disposable Lilly, Fleisch and Turbine
Disposable Lilly Transducer
The Lilly pressure system is very accurate, and comes individually pre-calibrated from the factory.
Its disposable system prevents cross contamination between patients, and its ergonomic design is very comfortable when performing pediatric tests.
Nowadays, it is the most-used option in Primary Healthcare.
For greater safety and protection against the risk of disease transmission, it can be used with a bacterial filter.
Fleisch Transducer
The SIBELMED Fleisch transducer features an accurate pressure sensor.
It is used in a numerous pulmonary units.
It requires an antibacterial filter to ensure there is no transmission between patients.
Turbine transducer
Measuring transducer through a helix. This is the most affordable model.
It requires an antibacterial filter to ensure there is no transmission between patients.
